I would use 3 small on-board timers instead of a 'remote control' - just set
one timer (24 hr -when to sprinkle timer) for the times you want to have the
sprinkler going - a second timer (sprinkle timer) to activate at one end for a
set period of time - then when it 'times out' - use this output to activate
the third timer (travel timer) plus a relay to turn on the motor to move the
sprinkler to the other end of the fence - and then repeat the sequence.
